New description: [New technical field] A thin heat pipe structure, especially a channel that is interdigitated through the inner wall of the heat pipe to increase the vapor-liquid diffusion efficiency and make the heat pipe axial and radial. They all have a thin heat pipe structure that conducts heat. [Prior Art] The heat is apparent, and the apparent thermal conductivity is several times to several tens of times that of metals such as copper and aluminum, and is equivalent to a heat-related component. In terms of shape, the heat pipe can be divided into a heat pipe in the shape of a circular pipe and a heat pipe in a planar shape. In order to cool the cooled parts of the electronic equipment such as the CPU, it is easy to install on the cooled area, and the flat type heat pipe is used for money. With the miniaturization and space saving of the cooling mechanism, in the case of a cooling mechanism using a heat pipe, the heat pipe is also required to be thinned. A space is provided inside the heat pipe as a flow path of the working fluid, and the working body accommodated in the space is subjected to phase change and movement by bursting, condensation, or the like. Next, the operation of the heat pipe will be explained in detail. The miscellaneous pipe has a sealed cavity to transfer the pure thief (4) to correct the work _ the mization and the crane to carry out the heat. Therefore, the industry uses the heat pipe as a remote Μ Φ ^ ..., The heat pipe is placed in the heat-dissipating fin, and the low-private hair end of the bribe (four) part is filled with heat absorption evaporation, and the 29 pieces of the electronic reading of the brain (the heat transfer breeze generated by the evaporating hot electronic component) will go to the political fin. The heat of the 100208428 1003371542-0 M417531 is taken away by the cooling fan to complete the heat dissipation of the electronic components. The manufacturing method of the hot officer is to form a capillary structure layer by inserting a metal powder into a hollow pipe body and sintering the metal powder through the sintering method, and then the pipe body is vacuum-filled and read. The fluid is finally sealed, and the heat pipe needs to be made thin due to the demand for thinning of the electronic equipment. The uniform temperature plate and the heat pipe smoke - through the evaporation and condensation of the working fluid for heat conduction 'only - the difference is that the heat pipe is mainly used for axial heat conduction and the average temperature is the heat conduction of large area near surface and surface, as if The current electronic equipment is thinned 4', so in order to use it with the electronic equipment, it is necessary to make the heat pipe or the temperature equalizing plate as a thin design. The conventional technology is made into a flat plate shape by the heat pipe (four), so as to conform to the thin type =^=heat pipe to be made into a thin type primary system, the heat pipe is filled and sintered, and then the county is shaped, and the money is privately recorded and then sealed. First, the body of the hot official is flat, and then the inner chamber is extremely narrow, which causes the filling operation to be applied to the material. In the case of too narrow, it is too narrow, and it is heated. Although the heat pipe has a large _'=== effect, the radial thinned heat pipe is not easy to process; 4 100208428 1003371542-0 2. The capillary structure in the easy-to-break soil heat pipe; 3. The manufacturing cost is high; 4. The radial conduction is impossible. Heat. [New content] The main purpose of this creation is to provide a thin heat pipe structure with both heat conduction function in both axial and radial directions. Another object of the present invention is to provide a thin heat pipe fct structure manufacturing method which can be made into a thin heat pipe. For the above purposes, the present invention proposes a thin heat pipe structure comprising: an s body, a mesh body; the pipe body has a cavity, the inner wall of the chamber has a channel to the channel and at least one a channel, the first and second channels extending in a staggered manner, the mesh body having a plurality of meshes attached to the inner wall of the chamber. Through the creation of the thin heat pipe structure, the heat pipe can be made thinner, and the heat can be transferred both in the axial direction and the radial direction of the pipe body, thereby greatly improving the heat transfer efficiency. [Embodiment] The above object of the present invention, its structural and functional features, will be described in accordance with the preferred embodiments of the drawings. Please refer to the first, first, second, and second embodiments of the first embodiment of the thin heat pipe structure of the present invention, which is a perspective exploded view, a combined view, a perspective exploded view, and a partially enlarged view of the combined view. The thin heat pipe structure 1 comprises: a pipe body u and a mesh body 12; 'the pipe body 11 has a chamber 111 and a working fluid 13 (as shown in Fig. 8), and the inner wall of the chamber 111 1111 has at least one first channel iHia and at least one second channel 1111b, and the first and second channels 111a' mib are interdigitated with 100208428 1003371542-0 5 extension; the mesh body 12 is attached to the cavity The mesh body 12 has a plurality of grids 121, an inner wall 1111 of the chamber 111. The 5 metaphysical body 11 further has a first seal ln, a Zhang, a + Chu Π 2 and a second closed end 113. The closed end 112 and the second seal are opposite to the chamber 111. The third section is the cross-sectional view of the tube of the second aspect of the invention. The structure of the body is the same as that of the embodiment. Therefore, the description will not be repeated here. The difference between the foregoing first embodiment is that the surface of the first and second channels lllla, llllb has a sintered powder 5, and the sintered powder 5 is a copper powder and a bristles thereof, and this embodiment is made of copper. Powder is illustrative but not limited. Please refer to the fourth ffl, which is the cross-sectional view of the third embodiment of the heat pipe structure of the present invention. The structure of the present embodiment is the same as that of the first embodiment, and therefore will not be described here. The difference between this embodiment and the foregoing first embodiment is that the first channel lllla is extended, and the second channel nnb is arc-shaped, and the first and second channels lllla and The lbs are interlaced and form at least an interlaced portion nUc at the intersection of the first and second channels 111a and 111b. FIG. 5 is a cross-sectional view of the tube body of the fourth embodiment of the thin heat pipe structure of the present invention. As shown in the figure, the part of the structure of the present embodiment is the same as that of the first embodiment, and therefore will not be described again. However, the difference between the embodiment and the first embodiment is that the first channel 111a extends in a spiral shape, the second channel lulb extends in a spiral shape, and the first and second channels llUa The llllbs are interlaced, and at least one interlace portion 100208428 6 1003371542-0 llllc is formed at the intersection of the first and second channels Π1 la and llllb. The reference to the sixth embodiment is a cross-sectional view of the pipe body of the fifth embodiment of the thin heat pipe structure of the present invention. As shown in the figure, the partial structure of the embodiment is the same as that of the first embodiment, and therefore will not be used here. For example, the first embodiment is different from the first embodiment in that the first channel 1111a and the second channel liiib are disposed only adjacent to the first closed end 112 and the second closed portion of the tube body u. At end 113. Please refer to Figures 7 and 8 for a schematic diagram of the application of the thin heat pipe structure and a cross-sectional view of A~A, as shown in the figure 'When the pipe body 11 has a heated end 1 & and a heat sink end lib ' The heat receiving end 11a is in contact with the at least one heat source 3, and the heat dissipating end lib is in contact with the at least one heat dissipating component 4. In the embodiment, the heat dissipating component 4 is illustrated by a heat sink, but is not limited thereto. The heat source 3 generates heat, and the heat is absorbed by the heat receiving end 11a to cause the liquid working fluid 13a to be evaporated and converted into the vapor working fluid 13b, and the vapor working fluid 13b is transmitted through the gap between the mesh bodies 12 to dissipate heat. The end lib is conducted and cooled at the heat dissipating end lib, and condensed into the liquid working fluid 13a' via the cooled vapor working fluid 13b and passes through the first and second channels 1111a, 1111b on the inner wall of the chamber 111 of the tube 11. The 1111 diffuses and recirculates, so that the liquid working fluid 13a can be recirculated to the heat receiving end 11a along the axial and radial directions of the first and second channels 111a, 111b of the pipe body 11. Please refer to Figures 9 and 10 for another application diagram and BB cross-sectional view of the thin heat pipe structure of the present invention. As shown in the figure, if one side of the heated end 11a and the heat source 3 are set as the heat absorption side 11c, the opposite is true. The other side of the heat absorbing side 11c is a heat dissipating side lid, and the heat dissipating component 4 can be disposed on the heat dissipating side lid. When the heat absorbing side 11c absorbs the heat generated by the heat source 3, the liquid working fluid 13a is evaporated to a vapor state. The working fluid 13b is conducted to the heat dissipating side lid to be cooled, and the liquid which is condensed by cooling 100208428 1003371542-0 7 M417531 The working fluid 13a is returned to the endothermic side 11c along the first and second channels 111a, 111b to continue the vapor-liquid circulation. Therefore, the thin heat pipe structure 1 of the present invention not only has the effect of axial heat transfer', but also has the effect of conducting heat in the radial direction, and can increase its support through the mesh body 12. The thin heat pipe of the present invention has the effect of conducting heat in the axial or radial direction, so it has excellent heat conduction performance either as an axial guide or as a large-area heat conduction in the radial direction.
